Diagnostic criteria: 1. Age 50 years or older; 2. Myalgia and stiffness in at least 2 places in the neck, scapular girdle and pelvic girdle for more than 4 weeks; 3.

Generally, a small dose of prednisone 10-15mg/d is used, and after the symptoms are relieved in about 4 days and the blood sedimentation and C-reactive protein return to normal, the prednisone is reduced to 5mg/d for maintenance treatment for 1-2 years. Patients with combined temporal arteritis should be treated with prednisone 40-60mg/d, and the dosage should be gradually reduced after the symptoms are relieved. 2.Non-steroidal anti-inflammatory drugs; effective for patients with simple, mild PMR. 3, symptomatic treatment.
